Interworking: Set key_mgmt parameter for the temporary network block

Previously, this was left to the default (WPA-EAP WPA-PSK) value which
could potentially result in unexpected behavior if an AP were to enable
both WPA2-Enterprise and WPA2-Personal in the same BSS. While this is
not really that likely for APs supporting Interworking, it is good to
get the PSK option removed to avoid any issues with missing
passphrase/PSK configuration parameter.
